For each of the four long parallel straight conductors extending through the vertices of a square (30 cm square side) perpendicular to its plane, the current flows 10 A, and three conductors of the current flows in one direction, and the fourth - in the opposite direction. Determine the magnetic induction in the center of the square.
Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
